Subject: [PATCH 0/4] arm64: dts: rockchip: support mail and IPA thermal for rk3399

This series patches supported the mail in devicetree and used the
thermal IPA by default.

Verified with rk3399 kevin board on my github
https://github.com/Caesar-github/rockchip/commits/gru/next-stable-chromeos
The kernel is based on Linus's master branch and Heiko's
v4.14-armsoc-tmp/dts64 branch. ( The Linux version 4.12.0 for now).
---

Tested on Kevin board with bringing up ChromeOS.
OS VERSION:
    CHROMEOS_RELEASE_DESCRIPTION=9693.1.0 (Official Build) dev-channel kevin test

BIOS VERSION:

EC VERSION:
    Build info:    kevin_v1.10.217-24514961d 2017-07-03 07:46:36 wxt@nb

With the ARM's lastest mali driver TX011-SW-99002-r18p0-01rel0 on

And for thermal with IPA.
Try to run 'md5sum /dev/zero &' and octane/benchmark scripts to go up the temperature.
>From the scripts to have a look at the actual control.
